The desktop client requires Java 8 or greater. You can download and install the latest version of Java from here.

Warning

Be sure to download the 64-bit version. Browsers are usually 32-bit and the Oracle website generally proposes 32-bit Java instead of the 64-bit version.
If you already have Java installed, use the java -version command to check the architecture. If 64-bit does not appear, the version is 32-bit.

Warning

On a Mac platform, note that you must install Oracle JDK instead of the usually-required JRE.

Once installed, the Desktop Client is automatically kept up to date through an online update system. When it connects to a Centreon MAP server it automatically downloads and installs the latest version compatible with the server.
Auto-update requires your computer to have internet access.
